   <span class="function"><strong>PDO::errorInfo()</strong></span> only retrieves error information for

   <span class="function"><a href="pdo.query.html" class="function">PDO::query()</a></span> and invoke an error on the statement
   handle, <span class="function"><strong>PDO::errorInfo()</strong></span> will not reflect the error
   from the statement handle. You must call
   <span class="function"><a href="pdostatement.errorinfo.html" class="function">PDOStatement::errorInfo()</a></span> to return the error
   information for an operation performed on a particular statement handle.
